My youth story, a crossover anime, turns out, is FGO!

"This is the moment!"

At the moment the barrier shattered, Makoto Aoki moved away from Tiamat to warn everyone.

Even if he attacked her vital points, Tiamat still had such a huge body that she, as a physical being, would not be so easily destroyed!

Karna was the first to respond to Makoto Aoki's words.

A blazing and dazzling sun unfolds behind you, echoing the great sun in the distance, as if another great sun has descended upon this place.

His golden armor was cracking inch by inch, revealing his pale but strong body and bleeding skin from the loss of his golden armor.

Karna's mother, Quinti, fearing the prospect of becoming an unwed mother, requested the golden armor and earrings from Surya to protect her son. Because they were formed from light itself, even the gods could not destroy them.

The golden armor has long been integrated with Karna's body, able to shield him from many injuries and curses. In exchange for this innate protection, Karna will also possess the most powerful god-slaying spear.

A spear of light that is enough to bring down the gods with just one strike.

A spear of annihilation composed of lightning. When Indra took away the golden armor, he gave it to Karna because of his noble attitude and felt that he had to repay him.

Revealed in exchange for golden armor, this weapon is equipped with a powerful "anti-god" spear, acquired through immense defensive capabilities.

In the anecdote of Karna giving the Golden Armor to Indra, Karna relinquished and dismantled the Golden Armor, thus obtaining the Spear of Godslayer.

Even the King of Gods would find it difficult to control the spear of light. A single strike, stained with the blood of those stripped from their bodies, could sweep away all filth. Its power was sufficient to utterly destroy all "single" existence in the world—living, non-living, and even any object, including magical beasts, phantom beasts, divine beasts, humans, shields, armies, cities, barriers, and gods. Nothing could withstand it, except for the "world." Even a "god" could not destroy the "world." Even if everything, including gods, were to perish, the world would still exist.

At this point, Tiamat, having lost the power to reverse creation, no longer exists as a world, but as a single entity.

The golden spear in Karna's hand changed its appearance, and the brilliance in his eyes was unmatched.

"Understand the mercy of the King of Gods."

"Indra, watch carefully."

"Extinction hinges on this single stab—"

At this moment, Ramses II, who was a little annoyed that the "Great Composite Temple of Radiance" had not achieved a decisive effect, came over to tease Gilgamesh: "Golden one, I have made contributions, you are not going to just keep throwing out Noble Phantasms, are you?"

Ramses II pointed at Karna: "In the end, it is the Pharaoh who will resolve everything, and as the sun, he is naturally the Pharaoh!"

That's true. At least the Great Radiant Temple is one of the strongest defensive artifacts. Its combination with the Great Wall meant that Qin Shi Huang wasn't struggling alone and was able to maintain control over Tiamat.

Karna, as the son of the sun god, was also regarded as a pharaoh by Ramses II... although it was only his own opinion.

"Hahahaha, what kind of joke is that, you idiot!" Gilgamesh raised his head and said arrogantly, "There is only one king in heaven and on earth!"

Gilgamesh's crimson serpentine eyes caught sight of Tiamat's massive figure, and a rare air of composure appeared on his face.

Let this strike be a farewell ceremony!

Golden ripples spread around his hand, and Gilgamesh drew out a golden object that resembled both a key and a sword.

Countless red lines rapidly extended upwards from the key in Gilgamesh's hand. These enormous yet light crystals quickly filled every inch of the field of vision, resembling branches of a tree or some kind of extremely complex three-dimensional circuit.

These red lines quickly took root in the invisible void and began to analyze the state of the world.

Gilgamesh's Noble Phantasm is derived from the concept of world creation in Mesopotamian mythology, simulating the scene of the creation of the world, and its power is capable of tearing the world apart.

In contrast to Tiamat, it still represents the ability to create worlds.

"At the beginning of creation, nothingness also offered its congratulations."

The red lines and crystals all converged, transforming into the "blade" of the golden key in Gilgamesh's hand. The three black pillars, symbolizing heaven, earth, and humanity, rotated in different directions, and the red magic on them gave people a suffocating sense of oppression.

As the cylinder rotated, a violent hurricane suddenly arose in the vacuum. The torrent of magic formed a pillar of wind that pierced through the sky as the cylinder rotated, and tiny black cracks could even be seen being torn apart in the surrounding space.

"With my sword of discord, I tear the world apart. Encircling the mortar of stars, the celestial hell is the end of the eve of creation—"

On the other side, golden mist gently rose and floated all around.

"Seal·Thirteen Decision·Start! (Thirteen restraints lifted, roundtable decision begins!)"

Golden mist rose around the silver knight, like the breath of stars, bringing a dazzling and awe-inspiring feeling.

The golden mist seemed to absorb the surrounding light, and the world seemed to fall into silence. However, the places where the light clustered together were so dazzling, just like the figure holding a sword in the center of a golden ocean.

"You have to be serious sometimes."

A frivolous, flamboyant, and ethereal female voice rang out.

"This battle must be a battle for survival."

—Kai

As King Arthur's cousin, Caesar offered his blessings.

"This battle is a battle against those stronger than ourselves."

—Acknowledgment, Bedivere

Bedivere, who served King Arthur to the very end, offered his hopes.

The Silver Knight still held the Holy Sword, and a golden light flashed on the sword, seemingly signifying the breaking of a seal.

And this roundtable decision, made by only one person, continues.

"This war is not a war that betrays humanity."

—Acknowledgment, Gahrez

"This battle is not a battle against the elves."

—Acknowledgement, Lancelot

"This battle is a battle to punish evil."

—Admitted, Mordred

"This battle is not fought for personal gain."

—Acknowledgement, Galahad

"This battle is a battle of noble honor."

—Admittedly, Gawain

"This battle is a battle for the brave to fight side by side."

—Acknowledgment, Tristan

"This battle is not one where those who seek goodness wield their swords."

—Acknowledgment, Gareth

The hurricane around Old Sword transformed into a massive tornado, while the holy sword in his hand, forged from a planet and designed to deal with extraterrestrial enemies, possessing the power to cleave two planets, finally radiated a truly sacred and dazzling brilliance, as if wiped clean of dust.

"This battle is the battle to save the world."

Finally, the Knight of Azure Silver said in a deep voice.

—Acknowledgement, Arthur

When the seven seals are broken, the Star Sword will reveal its true power. The old sword changed its grip, with the tip pointing downwards, and swung forward with an indomitable spirit.

The voices of the three top-tier Heroic Spirits overlapped, and they simultaneously chanted the true name of their Noble Phantasms.

"Burn completely—Sun Wheel, submit to death (Vasavi Shakti)!!"

"Let your death settle everything—Enuma Elish, the star that created the chaos between heaven and earth!!"

"—Excalibur! (Sword of Excalibur!)"
